It writes and reads necessary management data for processing and assembling parts to the transponder to identify the parts and manage the process in each process of the manufacturing line. The hardware of the interrogator and the responder is provided with a microcomputer, and a communication means for transmitting and receiving data between the interrogator and the responder.

[0003]

By the way, at the time of startup and maintenance of the individual identification device by the above-mentioned radio communication system, the interrogator of the individual identification device is used to read and write data with the responder. At this time, it is necessary to specify the address of the memory in which the data is stored for the responder. In this respect, the conventional apparatus requires a lot of key operations, is complicated, takes a long processing time, and is likely to cause an operation error, which imposes a heavy burden on the operator who operates the interrogator.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and an object thereof is to provide an individual identification device which improves the operability of an operator who operates an interrogator and can significantly reduce the work load. It is in.

[0005]

In order to solve the above-mentioned problems, in the individual identifying apparatus of the present invention, a means for creating and storing a plurality of screens to be displayed on a built-in display device in the interrogator, and the screen The key input means for selecting, the means for displaying the data received from the responder on the selected screen in association with each other, and the response transmitted from the responder in response to the interrogation of the data transmission instruction from the interrogator. Means for determining the success or failure of communication and displaying the result of the determination on the screen of the display device.

Further, as an embodiment of the above-mentioned structure, the interrogator detects a light key input and displays a data writing guide screen on the display, and a screen corresponding to the screen selection key input. To display on the display, a means to detect the input of the data writing key and display the contents of the writing data on the screen, and a means to detect the input of the execution key to instruct the responder to write the data. A configuration including a means for interrogating, and further, an input key for inputting a comment displayed on the screen of the display on the interrogator, a means for storing the comment created by key input, and a selected screen There is a configuration including means for displaying the comment.

[0007]

With the above configuration, the key operation necessary for the data read / write operation with the interrogator is registered in advance in the interrogator, and the operator operates the key in accordance with the predetermined procedure. Pre-stored operations and processes are performed in response to individual key inputs, data is read from and written to the responder, and the contents of the read data and write data and the success or failure result of each operation are displayed. Display on the screen of the display unit equipped with the interrogator. As a result, the predetermined work can be performed with a simple key operation, and the burden on the operator is greatly reduced.
